ABSTRACT:
An automatically operating sewage purification plant for industrial and domestic sewage systems, comprising at least one conduit for conveying untreated sewage to at least one first chamber for preliminary sedimentation in which larger solid particles are separated out, at least one second chamber which communicates with the first chamber via at least one delivery conduit and in which partially purified supernatant liquid that flows in from the first chamber undergoes a chemical purification process. Each second chamber is provided with an outlet conduit for discharging purified supernatant liquid. Each second chamber is provided in its upper part with a supernatant receiving device which receives the partially purified supernatant liquid from the first chamber and which is adapted to pivot about an axis when filled to a predetermined level and therewith deliver its load to a cyclone arrangement. The plant also includes a device for delivering to the cyclone arrangement a chemical or chemical mixture in liquid form. The cyclone arrangement has a central opening through which now purified sewage water is discharged through an outlet pipe.
